Alright so it looks like "ga116" is not defined in the script. This is causing a NameError in the game/gallery.rpy file at line 1018. To fix this error, the creator need to ensure that ga116 is defined before it's used in the script. He needs to locate the Definition of ga116: Check if ga116 is defined somewhere else in the script files. It could be a variable, function, or a class. when he find its definition, he has to make sure it's accessible in the scope where it's being used. Define ga116: If ga116 is not defined anywhere, he needs to define it. Based on the context of the script, ga116 could be a variable holding some data or an object. Guessing its for a gallery img number 116 or something. Not sure but yeah.
Cant find it sadly since I cant access it all but if someone is subbed to the guy on Patreon, pls send him this
